Renewable sorbent material and method of use

A method, comprising:

• binding a base material comprising a first compound to a support;
• and
• reversibly binding an active material comprising a second compound to the base material, wherein the second compound comprises at least one functional group.

A method, comprising:

• exposing a solution comprising an initial concentration of a target species to a material comprising a support, a base material comprising a first compound covalently bound to the support, and an active material comprising one or more second compounds reversibly bound to the base material, the second compound comprising at least one functional group capable of binding at least a portion of the target species to the functional group, wherein at least a portion of the target species binds to the active material when the solution is exposed to the material, thereby producing bound target species;
• and
• delivering a stripped solution based on the exposed solution.
